Implement vsproj support

[nycdotnet]

This pull request adds support for Visual Studio project files in grunt-ts.

WORK IN PROGRESS - DO NOT MERGE

Examples:

vsproj_test: {
    vs: 'test/vsproj/testproject.csproj'
},
vsproj_test_config: {
    vs: {
        project: 'test/vsproj/testproject.csproj',
        config: 'Release'
    }
},

Known Issues:

• I upgraded tasks-internal with this latest version - upgrade again before going final since this one still has bugs.
• Implement vsproj_ignoreFiles_test (done 0734468)
• Implement vsproj_ignoreSettings_test (done 0734468)
• Ensure proper errors when using vs with files (will not be supported) (warning implemented in eaec13a).
• tslint is broken (doesn't handle TypeScript 1.4 union types). (Fixed in d877eb0 by upgrading package.)
• Blocked by bug in tslint-path-formatter. (removed this dependency in 78ca831)
• remove temporary nycdotnet grunt task (done c13488b)
• fix explosion of .baseDir.ts files (Looks like this is solely due to the tests failing and clean:testPost not running (it was)).
• fix transform regression: test\transform\ts\rootLevel.ts test (getting a line "/// Unknown transform ///ts:(.*):generated" added.) Fixed in 2a2cd0b and 49aa9a1)
• update documentation including screenshots of Task Runner Explorer in VS 2013 (the docs are updated, but TRX is still too unreliable to recommend).
• make sure there are no inappropriate warnings when using vs (such as comments/remove comments) (fixed in 8adcbba).
• make sure UNC paths aren't broken (ts.ts line 204). (actually going to just decide this isn't supported. I don't believe that they worked before either)
• fix typo in suppressImplicitAnyIndexErrors warning (not plural) (fixed in 6782332)

This is a pretty significant change and I may need a bit of help. If anyone can offer some assistance regarding git-fu (reducing the non-changes changes - if possible or ideas for how to crunch them into a single commit), and also help identifying/fixing the cause of the transforms regression (I put a screenshot of the comparison of the expected and actual file.

@Bartvds Any chance you can investigate Bartvds/tslint-path-formatter#4 ? This update to grunt-ts is now blocked by the bug it fixes. I'm willing to do it if you give me permissions to the repo.

It's just the transform problem that I am scratching my head on.

The diff does contain changes to transformers.ts : https://github.com/TypeStrong/grunt-ts/pull/215/files I would start with reverting those if those were not intentional ❤️
